Specification of Letters Patent.

Patented July e, 1915.

Application filed September 1, 1914. Serial No. 859,685.

To all whom it may concern:

Be it known that I, FAUNT Ln Roy GAR- rnn, a citizen of the UnitedStates, residing at San Mateo, in the county of San Mateo andState ofCalifornia, have invented new and useful Improvements in Vehicle-Wheelsand Demountable Rims, of which the following is a specification.

This invention relates to vehicle wheels, the object in view being toprovide a demountable tire carrying rim, the rim and wheel being soconstructed, combined and related to each other that the rim may beeasily demounted from the wheel and as easily remounted thereon withoutdisturbing the relation existing between the said demountable rim andthe tire carried thereby.

The main object of the present invention is to provide in connectionwith such a demountable rim and wheel, a single operating device forlocking and unlocking the rim in relation to the wheel and at the sametime efiecting a tight and reliable fit between the rim and wheel whichwill avoid all rattling of the rim under hard service.

With the above and other objects in View, the invention consists in thenovel construction, combination and arrangement of parts, as hereindescribed,

In the accompanying drawings :-'Figure 1 is a side elevation partly insection of a portion of a vehicle wheel and rim embodymentary insideperspective view of the rim showing one of the lugs. Fig. 3 is afragmentary perspective view of the wheel showing the locking slide.Fig. 4 is a similar view showing one of the L-shaped grooves ordepressions and the wedging floor thereof. Fig. 5 is a detail sideelevation of the structure illustrated in Fig. 3, showing the adjacentcover plate removed; and Fig. 6 is a cross section, taken in line withthe shaft of the eccentric.

Referring to the drawings A generally designates a wheel embodying theusual hub 1, spokes 2 and felly 3.

In carrying out the present invention the flange 4 extending entirelyaround the wheel and against which the demountable rim is adapted toabut when slid laterally over the folly. In its peripheral face thefolly 3 is provided with a circular series of L-shaped grooves ordepressions designated generally at B and each comprising a longitudinalporillustrated and claimed.v

provided at one side with a stop to facilitate the tion 5 embodying aninclinedwedging floor 6 and a portion 7 which extends transversely ofthe tread of the wheel and intersects the longitudinal portion 6, thetransverse portion 7 opening out at the side of the wheel for a purposewhich will appear.

At one point the tread or peripheral surface of the wheel is formed witha T-shaped depression or slot designated generally at C, said slotcomprising the portion 8 which extends longitudinally of the wheel andthe transverse portion 9 perpendicular to the portion 8 and opening outat the side of the folly in the same manner as the portions 7 of thedepressions B. Mounted to slide lengthwise of the longitudinal portion 8of the slot C is a locking slide 10 provided intermediate of its endswith a notch or depression 11 which is adapted to move into and out ofregistry with the transverse portion 9 of. the depression for a purposewhich will hereinafter appear.

The slide 10 is provided with a circular opening 12 therein in which ismounted an oscillatory disk 13 having an eccentric hole 14 therein whichis of non-circular shape and adapted to receive the non-circular portion15 of a short shaft or spindle 16 which is journaled in a hole 17 in thewheel and has its outer projecting end squared as indicated at 18 toreceive a wrench or similar implement for turning the same. Fast on theouter end portion of the shaft or spindle is a ratchet wheel 19 which isadapted to be engaged by a detent 20 normally held in enthe depression.

The demountable rim indicated generally at D is provided with the usualtire holding flanges 22 one of which may be detachable application andremoval of the tire. The demountable rim D is vided on its inner facewith lugs 24 corresponding in number with the depressions in theperipheral face of the wheel, each of said lugs 24 being preferablyformed with a beveled extremity 25 adapted to ride against one of theinclined floors 6 of the pro-v depressions B. In one of its side facesthe rim D is preferably rabbeted as shown at 26 to receive and fittightly against the flange 4c of the wheel. If desired said rim may beprovided at its opposite side with an inwardly extending annular flange27 to bear against the adjacent face of the felly.

From the foregoing description taken in connection with the accompanyingdrawings the operation and relation of the wheel and demountable rimwill now be understood.

Preparatory to placing the rim on the wheel, the locking slide 10 ismoved to a position which will cause the notch 11 therein to registerwith the portion 9 of the depresssion or groove C. The deinountable rimis now slid laterally over the wheel so that the lugs 24 will enter thedepressions in the peripheral face of the. wheel. When the rim has beenmoved against the flange 4, the lugs are all in line with thelongitudinal portions'of the depressions and one of the lugs is restingin the notch 11 of the locking slide. A wrench is now applied to theshaft or spindle and the latter is turned thereby causing the lockingslide to actuate the lug engaged thereby, the result being that thedemountable rim is given a partial axial movement or turn upon thewheel, the result being that the remaining lugs are caused to rideagainst the inclined floors of the depressions in the wheel, therebyproducing a wedging action between the rim and wheel which will preventany possibility of rattling between the wheel and rim. The detent 20then engages the ratchet wheel on the shaft or spindle and prevents thesame from working loose and permitting the locking slide to movebackwardly. To remove the demountable rim, the operation just abovedescribed is reversed, the detent 20 being moved out of engagement withthe ratchet wheel and the spindle being turned so as to move the lockingslide until the notch therein registers with the portion 9 of thedepression C The rim may now be slid laterally off the wheel.

The rim D is recessed at 25 to admit of a slight outward or radialmovement of the slide 10 as the latter is operated by the disk 13.

In order to avoid any possibility of the automobile rim rattling orchattering on the felly, a thin piece other suitable noise absorbingmaterial may be applied to the floor or bottom of each of the recesses Bin the felly as illustrated in Fig. 1, against which the projections 24on the automobile rim bear when the rim is in place on the wheel.

28 designates a cover plate which incloses the space in which the parts19 and 20 are arranged so as to exclude foreign matter from said parts.The plate 28 is formed with a curved slot 29 to receive theoutwardly-projecting end portion of the looking dog 20 as illustrated inFig. 3. While the members 19 and 20 are covered in by the plate 28, theeccentric and dog may be readily operated from the outside as will beapparent in Fig. 3.

That I claim is 1. The combination with a wheel having L-shapeddepressions in its peripheral face, of a demountable rim having internallugs to enter said depressions when the rim is slipped laterally uponthe wheel, a locking slide carried by the wheel and movablelongitudinally of the peripheral face of the wheel, and means foroperating said slide causing it to engage one of said lugs and partiallyturn the rim around the wheel to establish an interlock between'saidlugs and walls of the depressions.

2. The combination with a wheel having L-shaped depressions in itsperipheral face, of a demountable rim having internal lugs to enter saiddepressions when the rim is slipped laterally upon slide carried by thewheel and movable longitudinally of the peripheral face of the wheel,and means for operating said slide causing it to engage one of said lugsand partially turn the rim around the wheel to establish an interlockbetween said lugs and walls of the depressions, and means for lockingsaid slide.

In testimony whereof I afix my signature in presence of two witnesses.
